Theros is ruled by an awe-inspiring pantheon of gods. Mortals tremble before them, feel the sting of their petty whims, and live in terror of their wrath. It is a plane where barbaric, cave-dwelling minotaurs descend on wayward travelers. Giants stalk the land, drawing strength from the terrain on which they tread. Massive krakens prowl the depths of the sea and sirens lure sailors to their demise. Amid such colossal perils, mortals must find a way to endure. Yet on Theros, the hero’s mantle is raised highest.
Not only have the mortals endured, they have managed to thrive, for Theros is also a plane where civilization is protected behind the walls of great poleis, each city-state a bulwark against the raging monsters that roam the more savage places of Theros. Meletis, the polis of learning, progress, magic, and devotion to the gods, is a testament to the achievements of civilized humanity. It is hemmed in by vast golden wheat fields and the Siren Sea, and defended by their Reverent Army. In the polis of Akros, martial prowess is held in the highest esteem. Akroan warriors have reached near-mythic status throughout Theros. The imposing cliff-top fortress of Akros lies at the center of a network of outposts that serve to protect the rest Theros, a fact that comforts many Therans. Setessa, the isolated polis surrounded by concentric rings of forest, is fiercely independent. Strong bonds connect its inhabitants, and all in Setessa share a veneration of nature.
A pantheon of gods rules over Theros. Each god has different attributes, desires, temples, and worshippers. Like the other planes of the Multiverse, Theros’s magic is derived from the five colors of mana, and each god draws power from specific mana sources. Each maintains influence over the mana that reflects their respective domain.
The Land of Nyx
When Mortals sleep and dream on Theros they are said to “visit Nyx,” the proverbial land of night and home of the gods. Dreams are seen as gifts from the gods. When they appear to mortals, the gods are actually infused with Nyx, so that the night sky is intertwined with their physical form. Gifts given from the gods to mortal heroes reflect their Nyx origin as well.
